DORNIER Do-27 aircraft report
The Do 27 is one of the best choices when it comes to operation
from small air strips. High quality workmanship combined with state of the art engineering
made the Do a success in the late 50's.

Dornier Do28 (a twin engine 27)

History:
The Dornier Do27 was the first aircraft to enter production in Germany
after World War II. Claudius Dornier recommended activities in Spain in 1949, his Oficinas
Tecnicas Dornier working closely with the Spanish CASA.
The initial fruits of this collaboration were evident with the first flight of the Do25 in
June 1954. Prepared to meet a Spanish air ministry specification, the STOL transport
aircraft was powered by a 150hp ENMA Tigre engine.
Developed from this, the prototype Do27 was flown on 8April 1955.
Production took place in Germany, the first example flying in October 1956.
The production began, now equipped with a Lycoming GO-480 engine, mainly
the military version Do27 A and dual control Do 27 B but the Do was although used for
passenger transport.

The strutless high wing concept proved ease of access to the cabin. Full
wingspan slats and large flaps give an amazing STOL capability. More than 600 were build
before production ended during 1965. By far the largest user was the Federal German
Republic, another early customer was the Swiss Flugwaffe, whose aircraft had wheel/sky
landing gear. Other were supplied to Belgian and Israeli airforces.

Variants:
Do27 H: civil or military version powered by a Lycoming
GSO-480 engine with 340hp.
Do 27 Q5: civil version, similar to Do 27 A
Do 27 Q5-R: restricted category, equipped for operation
by pilot only in agricultural or forest dusting/spraying
Do 27 Q6: similar to Q5, but completed to the
certification requirements of the FAA.
Do 27 S: designation of a floatplane
| The Do27 S1 was similar to the Q1 model. One aircraft was build s/n
2023 and after some changes renamed in S2. The S stands for "Schwimmer" = float.
The Do27 was lost by accident 02/09/1972. |
 |
Do 27 T: prototype
 |
The Do27 T1 was similar to the Q4 model. The powerplant was a
Turbomeca Astazou II turbo-prop engine with 530HP. Only one of these skyrocketing planes
was build s/n 2068. |
After the certificate expired (1961) there are no more information available. The
F- in the immatriculation shows that it was a French aircraft and the -W stands for
experimental.
Do 27 A: light utility transport STOL aircraft, powered
by one Lycoming GO-480-B1A6 engine and a Hartzell Propeller.
Data:
Performance: speed 120kt, economy cruise 100kt with consumption of 14galUS
Weights: empty 1130kg (2491lb) MTOW 1850kg (4079lb)
Dimensions: span 12.00m 939(ft), length 9.60m 31 ½ ft
, wing area 19.40mx2 (208.83 sq ft)

Today, more than 30 years after the last Do 27 left the production line,
there are maybe 100 Do's still in flyable condition. Most of them are based in Europe and
some of them are for sale.
There is a small group of owner that never will consider selling. They
love their Dos, arrange annual meetings, swap parts and information.

Already before in 1985 a small number of Dos came to the US, imported from Israel. But like in the 80s
where all used American aircraft were sold out, today the flow is reversed and since April
one more Dornier, a used European build aircraft, is in the United States. (enjoying the
ferry-flying on its own, the direction across the pond doesn't matter)
The constructor when designing the aircraft, never had this in mind, but
the Do27 paired with good preparation can do the task easily. There are three basic
concerns besides the weather; the slow cruising speed (about 100kt), the limited range
(when only main tanks are standard) and the cross wind landings on some lonely airports in
the North Atlantic.

One major difference is the wing profile.
| normal wing profile
 |
Lets look at a normal wing. We want to fly slow, but
reducing speed meens reduced lift. To compensate this we have to increase the angle of
attack. The graphic shows what happens. |
| Now we want to fly really slow. And we modify the
airfoil a little to do this. Look the airflow and understand what makes the Do27 differnt. |
